The main function of a pressure transmitter is to transmit pressure signals to electronic devices, and then display pressure on a computer. The principle is roughly to convert the mechanical signal of water pressure into electronic signals such as current (4-20mA). The pressure and voltage or current are linearly related, generally proportional. Therefore, the voltage or current output by the transmitter increases with the increase of pressure, resulting in a relationship between pressure and voltage or current. The two pressures of the measured medium of the pressure transmitter are introduced into the high and low pressure chambers, and the pressure in the low pressure chamber is atmospheric pressure or vacuum, acting on the isolation diaphragms on both sides of the δ element (i.e. sensitive element), and transmitted to both sides of the measuring diaphragm through the isolation diaphragms and the filling liquid inside the element.
